Battery not charging

I have read lots of problems and most I see is that the battery wouldnt charge. The battery will not charge at all without any charge left in it. I also saw the solution of using a 9volt battery and leave it for certain amount of minutes to jump it. There is aa problem with these method, it sometimes kills and battery cell. There is a saver and faster way to jump the battery(which I also read somewhere in this forum).
1. get a hold of a USB cable for the computer(one that you dont usually use)
2. (not connected to the computer) you would need to cut off the end that plugs in you phone and then you will see 4 different wires. you will only be using the red and black wire so just strip those two.
3. take the battery off the phone, plug you phone to the wall charger w/out the battery, and connect the USB wire to you computer(make sure the red and black wires are not touching)
4. touch the red and black wires to the positive and negative end of the battery(the battery has labels of which one is the positive and negative part)
5. hold it there for 10 secs then quickly transfer the battery into the phone. after 3 secs of being in the phone, it should start right up.
this steps also depends on how long your battery has been dead. the maximum time you would do this is 3 times. after that and still not working, thats a confirmation of your battery being a done.

OMG thankyou so much my fone is now working ur a star

hahah
ur welcome

[Q] HTC HD2 running nand android will not turn on after battery died

Hey everyone been using this thread for a few months now it's so useful and I appreciate all the help. I know this has been posted before and I tried all the steps listed in the other thread but last night I let my phone die and when I plug it in it just boots up until the dark forces team screen before it starts over again i tried all the steps listed to get it to charge it just seems not to work. I was able to get into the magldr screen if I plug it in and hold volume and power off. From there I choose to power down and as long as it stays plugged in the orange light comes on but when I try to power it on nothing happens. Any advice would be greatly appreciated. Thanks so much

you cant charge it powered off without winmo, simple.
2 options, borrow battery long enough to flash wnmo on your phone, use your phone to charge battery, or put battery in another winmo hd2 to charge enough to start android. (or, let it sit for an hour or two, they sometimes recover a little charge, perhaps enough to boot. Boot with the usb in, cos ability to charge kicks in about half way thru teh boot process.

just to add a third option to my last post, , i let my battery die stupidly today, completely dead, , took an old usb cable, took the end off, black wire to - and red wire to + on battery, plug in usb cable, bite nails and worry for 1 minute, enough charge in battery to power on phone and boot enough for actual charging to start!
phewwwwww.

clever! brave! i like your attitude man

heh, not that brave, i didnt do it till id read about a hundred posts of people doing it on various devices.
@bakse, whats to explain?
get a usb cable,
cut the usb end off,
strip off the silver shielding,
find the red and black wires,
bare the ends,
attach the ends to the battery,, red to +, black to - (it says on the battery which is which)
plug in the usb cable.
After a minute, remove the wires, and try the battery in the phone, and hope it has enough power to start to boot and start to charge.
I read a fair few posts where people were holding the wires to the battery by hand, it is after all only a few volts dc, but i just wasnt that brave and went for gaffer tape.

Ha ha I have been a electrician for 15 years now and I can tell you with 100% assurance that the very small voltage that it takes to charge the battery of any cell phome will never ever affect you in any kind of way. You know I had often wondered if you could charge the battery in this fashion but was not completely sure as my I do not have a full understandimg of yhe iom bstteries yet.

hehe, i did 3 years as an electronics tech in the RAF, (long time ago) so im not usually that nervous around electricity, but i was last night, , generic 3 pin usb charger, generic usb cable, stories of batteries bursting, ANYTHING could have happened!
Ive tried it again today on an old dispensable htc elfin, held it for 5 mins, which is far longer than any posts ive read. Battery got warm, but not worryingly, and when i booted the elfin it had 2%, and managed fully booting plus ten minutes use, and id drained it completely before starting.
Im glad ive tried it, and now i hope i never need to do it again.

I just accidentally let my HD2 drain the battery, but this is the first time it hasn't come on. I did the USB cord trick and it seems to juice the battery, but when I finally got to the menu me being so caught up in the excitement that my phone wasn't bricked and that I could get it running again forgot to plug in my phone to be charged and it died again... Now I am using the hacked up USB cord to charge my battery, but is doesn't seem to charge it very fast and after about 10 minutes of letting it sit I get to the boot screen in Magldr but the battery dies mid boot. Now my question is should I leave the battery to be charged with the red and black wire USB trick and how long can I let the battery charge like that will it be fine for a few hours? Thanks for your replies in advance.

I don't know if it would be safe to leave the wire connected to the battery that long. To be safe I would only leave them connected to the battery for 15 to 20 minutes 30 minutes max. I would also monitor the battery making sure it is not getting warm/hot or that the batterry does not start to swell.As either of this things are signs that you should disconnect the wires.

Well it worked I got it charged to 5% and it took forever, but when I put it in my phone and it booted it said it was currently charging, but when I woke up dead again...

Charge with wall charger, not via PC,, the current of PC charging is way lower, so for an almost flat battery it may not be enough to both charge and run the phone.

Ive been doing this usb cable hack/trick what ever u wanna call it for a few days now my usb port is completely busted and ive got wp7 on it struggling to find anyone near me that will fix it as im not brave enough to take the phone apart and replace the micro usb port

HTC HD2 running NAND won't turn on after battery died
I spent couple hours last night after my phone accidently died and was unable to turn on even charging with wall charger, I read about trick with cutting usb or charging cable and attaching wires to the battery. Finally, I found great solution by myself. I simply connected phone to my car charger and in less than 1 minute it started Android and after couple minutes I was able to move my phone back to the wall charger

actually you can charge the battery with whatever you have handy.
I charged phone batteries with anything ranging from wires cut off from just about any li-ion phone charger (older nokias, samsung and se preferable), solar panels, other batteries (3 standard aaa alkaline batteries in series will do the job also - almost no risk to phone battery) electrochemical reactions (the best one, getting electricity from mustard using copper and zinc electrodes - also worked but you need 6 "custom made" mustard "cells" ), any sort of usb port etc
My choice depended on whatever i had handy at my disposal at that particular moment.
I also powered up phones with empty (or if i suspect them to be dead) batteries by placing 3 aaa rechargeable (ni-cd or ni-mh.. NEVER USE primary-non rechargeable batteries or any sort of alkaline/carbon based chemistry) batteries in series with the + and - leads over the ones in the phone but WITH the original phone battery connected (it won't work if you simply supply the phone with 3.7 - 4.3 volts.. the center phone battery pin is needed).
They all work and for a one time quick emergency charge, it will be fine (just don't make a habit on doing these to often).

My battery run out and it wont charge it when phone off

My htc hd2 wont charge and it wont turn on i need help i have the androind 2.2
NEED HELP!!!!

Hi,
Please read this thread.You might find some useful information in there.
http://forum.xda-developers.com/showthread.php?t=1028841

Either
1 borrow friend/shop with a hd2 running winmo to charge your battery,
2 borrow / buy battery to flash winmo then use your now winmo phone to charge it,
3 buy an external charger,
4 take an old USB cable, cut end off, strip back and find red and black wires,,red to plus on battery, black to negative (marked on battery) plug into USB slot and hold wires there(fingers are fine, you won't get a shock) for 30/40 seconds. Should be enough charge to start booting, charging will start about halfway thru boot, so get proper cable in straight away into wall charger.
I've successfully used 4 twice.

[Q] MAGLDR 1.13 battery wont charge unique

So I have read about MAGLDR 1.13 battery drain fix "*Fixed Power-Off-Cable-Plug-Stop. Phone now detects this situation and reboots. Battery controller inside LEO needs runtime control during charge, it implemented in OS." and Yes that works fine! However once im in my OS Hyperdroid, my battery dies instantly and my phone turns off and turns back on thanks to MAGLDR then repeats until I unplug my charger.
Why wont my battery charge once im in the OS
Side note - I have taken the batery out and charged it via USB Red on + and Black on - If i charge it for 30 sec it will boot to OS and have 0% once i stick the charger in it dies instantly and reboots
Side note 2 - "" If I charge for over a min via Red/Black +/- it will boot into os and give me a inaccurate battery reading of 60-65% and will not charge once I insert the charger.
Can anybody help?

It looks, you may have to charge battery a little bit in Bootloader screen before you can turn in to OS.

I think something might be wrong with your cable or charger. When you charge, do you get over 800ma or similar? Use current widget to check.
$1 gets you a reply

Have the charger plugged in all the time, and charging should start long before the rom finishes booting. The also, do use the wall charger, and not the pc's usb slot, which may connect and disconnect the time or two during boot, and stopping charging.

Thanks guys I have used 2 different chargers and it doesnt seem to be the case, im going to chop this up as I need a new battery, when i charge it manually via Red/Black to +/- for over 30sec it gives my O/S a false reading and says its 65% charged, ima buy a new one and see if this is the case.... I really hope this works and thanks for your help!

Restart loop while charging, Cant boot with Boot Loader.

Hi,
I have old T Mobile HTC HD2 with Android, (Used one, I received as gift from my friend)
This rom from http://forum.xda-developers.com/showthread.php?t=1022108
It have slow charging, but today, i found it with restart loop if in charging and not boot at all without charging, just boot with splash (Stick together) and vibration plus, then it restart again, the screen only light for less than a second, same when i try to boot to Boot Loader (VOL Down when boot) it show 3 colors less than a second, it cant boot with Boot loader.
I cant boot to make any Hard Reset.
Is it battery failed, or the it is Phone problem?.
The charger USB in the wall, also i test it on my PC, same.
Thanks in advance.

Could be bent battery pins, or flat battery. Magldr will not allow charging when android isn't booted, so if the battery is very low it cannot boot far enough to start charging, in which case see if you can charge the battery some other way, either
1 in a hd2 running winmo or cLK,
2 borrow / buy an external charger
3 cut end off a USB cable, bare red an black wires, connect black to - red to +, USB into wall charger and hold there for aminute or two.

Thanks samsamuel

If it is safe, I will buy female jack and take this wires from it, or maybe build external charger (IDK if it good idea).
Thanks

ive done it three times, plus i did teh same with a PMP battery that was discharged. works a treat. you can use your fingers to hold the wires on teh battery, you wont get a shock.
A minute is usually plenty (assuming you are using the wall charger, , if you are using a usb port, perhaps a touch longer.) as charging qwill start about 30 seconds into android boot sequence.

Worked, I get an old USB extension cable, cut it, and used the Red and Blue wires, but the problem in that cable the Red wire is (-) and the Blue wire (+), i used Avometer to test it before using it to recharge the battery manually (Oh my fingers) with 2 minutes, now my phone come alive and recharged again, Thanks samsamuel
